Automotive sensors convert physical quantities — temperature, pressure, speed, position, gas concentration — into electrical signals that the engine control unit and body control module use to manage fuel injection, ignition timing, emissions, safety systems, and driver aids. When a sensor fails or drifts out of calibration, the ECU falls back to default values, reducing efficiency and triggering warning lights. Keeping sensors in good condition is central to fuel economy, emissions compliance, and passing the MOT emissions test. CarParts247 stocks a comprehensive range of OEM and aftermarket sensors from Bosch, Hella, NTK, and Continental for virtually every make and model.
An OBD-II scanner reads live sensor data and fault codes. A sensor reading outside its expected range — or one that is implausibly static while others respond — points to the faulty unit. Compare live readings against specification: coolant temperature should climb from ambient to around 90 °C during a normal warm-up cycle; if it reads -40 °C permanently the sensor has failed open-circuit.
Bosch, NTK, and Continental manufacture sensors to OE specification and supply direct to the vehicle makers. Budget sensors may have wider calibration tolerances that cause the ECU to trim fuel or ignition timing unnecessarily. For emissions-sensitive sensors such as lambda probes and MAF sensors, OEM or premium aftermarket is strongly recommended.
